Abstract: PURPOSE:To efficiently manufacture the semiconductor device in which an internal base and an emitter are self-aligned by a method wherein a polycrystalline Si layer only is selectively removed by forming an impurity layer having a density gradient on the polycrystalline Si layer which is provided on a single crystal Si layer. CONSTITUTION:After a buried diffusion layer 51, an epitaxial layer and the like have been formed on a single crystal Si substrate 50, a non-doped polycrystalline Si layer 54 is formed on the whole surface. Then, impurity ions are introduced into the polycrystalline layer 54 in such a manner that the degree of density becomes high on the surface part and low at 10<18>cm<-3> or below on the interfacial part with the epitaxial layer 52. Then, an aperture 66 to be used for a base and an emitter is formed by performing an etching. In this case, the polycrystalline Si layer 54 only can be selectively removed without removing the epitaxial layer 52 by the above-mentioned impurity implantation. Subsequently, an ion implantation is performed through the aperture 66, and an internal base 72 and an emitter 84 are formed. Consequently, as the internal base and the emitter are formed using the polycrystalline Si layer 54 as a patterning mask, the number of masks can be reduced.

Filed: 1994-02-28
Abstract: PURPOSE:To surely send an alarm signal to a worker without receiving masking effect due to a noise by providing an audio frequency transmitting means which operates with a signal from a means for detecting external environment and is capable of adjusting oscillation frequency from the outside. CONSTITUTION:When the edge of the helmet H is put in the opening of a fixture 2 and inserted to the inner part against the elastic force of the fixture 2, an enclosure 1 is elastically fixed so that one point at the tip is brought into contact with the helmet H. When a dummy signal is inputted to a variable frequency oscillation circuit 7 to place a sounding means 9 in operation, the vibration of the sounding means 9 is radiated in the air as a sound and also transmitted to the helmet H through the enclosure 1 at the same time. When a variable resistor 8 is adjusted in this state, the frequency of the signal of a variable frequency oscillator 7 varies and the vibration of the sounding means 9 resonates to the helmet H. While the vibration of the sounding means 9 is recognized by the sense of hearing, the vibration is transmitted to the skull of the wearing person through the helmet H, so the alarm can distinctively be recognized.

Abstract: PURPOSE:To obtain a control output containing two signal components by obtaining a comparing signal by comparing the reference voltage and the first control signal voltage and obtaining a contro voltage by adding said signal to an output signal controlled by the second control signal. CONSTITUTION:A signal Vb supplied from a No.1 terminal corresponds to an AGC voltage of a video circuit in a video camera, becomes the first control signal and a signal Va supplied from a No.2 terminal determines a basic clip quantity of a chroma signal and becomes the control signal. Vref and Vb are compared and a current corresponding to its difference voltage flows through a resistance R3 and a transistor Q3 and since the transistors Q3, Q4 constitute a current mirror circuit, an output current Ic becomes that which corresponds to the difference voltage. On the other hand, by a voltage level of the voltage Va, a current I1 flowing through a transistor Q5 and an R5 is controlled, a current of I1+Ic flows to a resistance R6, a voltage drop corresponding to its current quantity is generated and it is generated as a control voltage Vc. In this way, an output of the control voltage can be made to have two kinds of control information.

Abstract: PURPOSE:To obtain the title hopper unit with good balance between the front and rear, by locating a hopper in the front side of a delivery case and communicating the hopper with the case at a point below a gear case for delivery drive. CONSTITUTION:A hopper 7 is located in the front side of a delivery case 14, therefore, the center of gravity of the fertilizing machine shifts forward, thus becoming favorable in respect of the balance between the front and rear of the main machine. Also, said hopper 7 is communicated with said delivery case 14 at a point below a gear case for delivery drive. As a result, fertilizer discharged from the hopper 7 enters said delivery case 14, the inlet of which is not located just above a delivery roll, thus enabling the denseness pressure of the fertilizer due to driving to be kept low and the roll-driving force to be reduced. Furthermore, such location of the hopper 7 at lower position will facilitate the replenishment of fertilizer.
